My dear

I think your mother is the best person to guide you

I will tell you some simple things.

Always take your meal in time.

Never take junk food.

Take 6 to 8 glass of water daily.

Take fruit & vegetables as well.

Keep balance between rest & play. Always take less salt & less pepper (red pepper).

It will help you all life to be healthy.

Until you feel hungry do not eat food.

You must play & do exercise.
